Lenovo G770 Fans not working

[Sargeraspa]

Contrary to everyone else's problems here my fans just not seem to be working anymore or something. I have switchable graphics with an integrated Intel and an AMD 1gb dedicated graphics card. When I switch to "high Performance" my lap top gets so hot, around 91 degrees Celsius. But when I switch to Power saving it stays a bit cooler. The trick is that I don't even hear my fans working most of the time. While playing SC2, a few times I've heard the fan go off(pretty noisy) and it cooled my computer off really fast. But most of the times it just builds up the temperature and becomes choppy as hell. I don;t remember it being this bad at first, but it seems that it has some kind of an issue now.

Pleae help, I'll try to download the latest drivers now, but I think I've already done that.

@Sargeraspa,

Ensure you have the latest BIOS and Lenovo Energy Management software.

Also ensure that the laptop is placed on a hard surface too if its not already on it. If problem persist then contact support to get the thermal checked.

Hey, thanks man. I know about keeping my lap top on the hard surface, learnt about that the hard way some years ago. What I'm wnderins is if I downloaded the Thinkvantage system update and it says that I have no applicable updates. Does that count for BIOS updates too?

Thanks!

Sargeraspa,

Lenovo G770 has ThinkVantage System Update? I thought that is suppose to be for ThinkPad system only?

Go to the link below and Select Win 7.

Then update the BIOS and Energy Management driver.

[Sargeraspa]

Yeah, apparently it doesn't (facepalm). I've downloaded the BIOS updates. Id doesn;t seem to make a difference so far. I think I've done the Energy management too, but I'll redo it just in case. Thanks!

[Sargeraspa]

I've already modified them half an hour ago. Now if I try to reinstall, it gives a windows fatal error. It cannot locate the downloaded directory from where it's supposed to install at one point. Weird. My computer temperature still seems to be around 60 degrees Celsius tho. I've downloaded Speed Fan. 

[Sargeraspa]

Well I've done that too. So I've installed the BIOS update, and restarted the computer (it did automatically) and now the energy management drivers too. The computer still feels hot tho. And Core0 and Core1 temperatures are at 62 Celsius. HD0 is at 47 Temp1 0C, 2 GPU's at 0C. Let;s try to run a game...

[Sargeraspa]

With running Starcraft 2 it warms up to 97C. Dang

Since that is done then contact support to get the hardware checked.

[Sargeraspa]

Ok, thanks man! I'm in Greece now. Is there a chance there is some kind of a toll free phone number for worldwide use?
